Title:
MULTIPLE STAGE VORTEX FLUID MACHINE
Document Type and Number:
Japanese Patent JP2004116509
Kind Code:
A
Abstract:

To provide a vortex fluid machine having a simple structure and high efficiency requiring no complicated machine work, which is low in price and is usable in multiple stages.

Two and three-stage compression is performed by an axial and lengthwise partitions in blade width and radial blade length, and a pressure of max 0.3 kgf/cm2 is achieved by a small-sized blower in three-stage compression. Thus, high compression ratio is achieved by a machine with a size much the same as vortex fluid machines on the market. Since the high compression ratio is achieved only by the blade part of a rotor in this structure, it can be adopted by either a blower or a vacuum pump. Machine work is necessary only to a plane surface and a cylindrical surface without any complicated work. Furthermore, the number of parts is only 5 or 6, thus high efficiency and low cost are achieved.
